my idle seems to have a mind of its own, i think it's the idle valve but dont want to change it unless i have to? being a bit tight fisted

 

could be maf/lambda also

 

maf? yeah could be, was told they do give a few problems

 

maf

 

Nice car btw

 

you seem certain?

 

thanks, do try and look after it, done 92000 miles now

 

Idle control valves are £298 from subaru

Have you done a error check yet ?

 

Would help to know what year of car, some MAF's are very robust some are fragile.

 

good job when mine was foofed jase @ scoobybits had a spare for £25 then

 

well ordered a maf now, £98, think that is the problem, i'll find out tommorrow when it turns up, oh, the car a P1 year 2000

 

MY99 and MY2000 are prone to failure of the MAF, don't forget to re-set the ecu after you fit it, i would say it would be that on that model.
You can use the connectors under the dash or just leave the battery off for a while, this will reset the ECU.

 

fitted the maf, seems fine now, bit more responsive too, hope i get a few more miles to the gallon, thanks for all your advice!
